What is M27500 cable?
M27500: special purpose and power cable of 1 to 15 MIL-spec basic wires, shielded, jacketed or both. Rating: basic wire, shield and jacket set the temperature (Table IA, IB). Standard: MIL-DTL-27500H (1997, cancelled 2001); NEMA WC 27500 for new procurement.
MIL-DTL-27500H, 10 December 1997, distribution A (standard, read on EverySpec): 1.2.1 the cable is identified by the specification number, then 1.2.1.1 the identification method of the wires with the shield coverage ('-', F, A, G, B, K, L for 85 %; C, H, D, J, E, M, N for 90 %), 1.2.1.2 the conductor size (AWG), 1.2.1.3 the basic wire symbol (Table I: SD = MIL-W-22759/34 ...), 1.2.1.4 the number of wires (1 to 15 shielded, 2 to 15 unshielded; 10 to 15 only 12 AWG and smaller), 1.2.1.5 the shield (Table IA: U none, T tin-coated copper round 150 C, S silver-coated copper 200 C, N nickel-coated copper 260 C, F stainless steel 400 C ...; the double-shield letters V, W, Y, Z ...), 1.2.1.6 the jacket (Table IB: 00 none, 01 PVC 90 C ... 23 XLETFE 200 C; 51 to 74 the double jackets). Notice 1 (2001) cancels it; new acquisitions refer to NEMA WC 27500, which keeps the part numbers (Wiremasters guide, secondary: 'M27500-20RC2S06'). The owner's chart (MIL M27500.pdf) is an OCR copy of the same tables; its example 'M27500-22S03T23' is the part number M27500-22SD3T23 (22 AWG, 3 wires, tin-coated copper shield 85 %, white XLETFE jacket). The reader decodes the fields after the name.
